BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to rack supports and more particularly, to an apparatus for securing stemware on the rack of a dishwasher.

2. Description of the Related Art

A commonly known problem associated with washing stemware in a dishwasher is that the stemware often shifts or tips over during the washing process. When the stemware shifts or tips over, it often breaks or collects water and food debris that is normally washed away or contacts other dishes and breaks.

Dishwasher accessories specifically designed for holding stemware on the rack of a dishwasher have been developed. For example, U.S. Pat. No. 6,394,285 (Arthurs et.al) discloses such an accessory that includes an elongated member with a vertical wire enclosed bore formed on one end and two gripper jaws formed on the opposite end. During use, the end of the elongated member is perpendicularly aligned over a vertical tine on the dishwasher rack so that the bore slides onto the tine. The two-gripper jaws are then attached to the post of the stemware to hold the stemware in an inverted, vertical position on the rack.

The one drawback with the accessory disclosed in U.S. Pat. No. 6,394,285 is that the height of the tine limits the size of stemware that the accessory can hold.

Another drawback is that only one accessory and, hence only one stemware, can be used on a single tine, which creates large open areas on the rack not filled with dishes.

A third drawback with the accessory is that the elongated member is not locked on the tine and is able to rotate on the tine when the dishwasher is operated. When rotation occurs, the stemware may tilt or fall to one side and collect water and food debris or contact other stemware or other dishes on the rack.

SUMMARY OF THE INVENTION

It is an object of the present invention to provide an apparatus for securely holding stemware in an upright position on the rack of a dishwasher.

It is an object of the present invention to provide such an apparatus for holding different sizes of stemware on the rack of a dishwasher.

DESCRIPTION OF THE PREFERRED EMBODIMENT(S)

Disclosed herein is a dishwasher apparatus, generally indicated by 10, for securing various sized stemware 90, in a stable, inverted upright position on a dishwasher rack 95. The first embodiment of apparatus 10 includes an elongated body 20 that is longitudinally aligned and attaches to a tine 96 on the rack 95. As shown in FIG. 2, the elongated body 20 includes a wide cylindrical lower section 21 with a longitudinally aligned bore 22 formed therein which enables the elongated body 20 to slide vertically over the tine 96. Formed on the proximal end of the lower section 21 is an optional longitudinally aligned side slot 23 designed to allow the elongated body 20 to rest against the horizontal framework 97 on the rack 95 thereby locking the elongated body 20 over the tine 96 and preventing its rotation.

The elongated body 20 also includes an upper, narrow neck section 24 designed to extend one to three inches above the upper end of the tine 96. In the preferred embodiment, the neck section 24 is octagonal in cross-section as shown in FIG. 3 and slightly smaller that the lower section 21 thereby creating a shoulder 26 that limits the downward movement to the clamping member 40 discussed further below.

FIGS. 3 and 4 show a second embodiment of the elongated body, denoted 20′, that includes a lower section 21′ and an upper, narrow neck section 24′. Attached to the lower section 21′ is at least one clip that snap fits the lower section 21′ to attach to the tine 96. In the preferred embodiment, the apparatus 10 uses two laterally extend clamping arms 27, 28 that include a u-shaped slot 22′, 22″ that snap fits tightly around the tine 96 to hold the lower section 21′ on the tine 96. The upper neck section 24′ is identical to the upper neck section 24 used on the first embodiment and used to hold at least one adjustable clamping member 40.

The adjustable clamping member 40 attaches at one end of the narrow neck sections 24, 24′. As shown more clearly in FIG. 5, the clamping member 40 includes two moveable jaws 45, 50 and biasing means disposed between them designed to force the two jaws 45, 50 together to grasp the center stem 92 on a piece of stemware 90 inverted and aligned vertically on the rack 95 and adjacent to the tine 96. Formed on the proximal end of the clamping member 40 is an octagonal-shaped socket opening 65 designed to slide over the neck section 24 on the elongated body 20. Because the socket opening 65 is octagonal in cross-section, the clamping member 40 is automatically fixed in position on the elongated body 20 and prevented from rotating thereover when the dishwasher is operated.

In the both embodiments, the elongated body 20, 20′ is approximately seven inches in overall length. The narrow neck sections 24, 24′ are approximately ¼ inch in diameter and approximately three inches in length. The lower sections 21, 21′ are approximately four inches in length and ½ inch in diameter. The longitudinal bore 22 formed on the elongated body 20 and the slot 22′ formed on the elongated body 20′ are approximately 3/16 in diameter. The length of the bore 22 and the location of the clamping arms 26, 27 are sufficient so that the entire tine 96 is engaged. Also, in both embodiments the neck sections 24 24′ are solid and a shoulder is formed between the neck sections 24, 24′ and the lower sections 21, 21′, respectively. With the first embodiment, the side slot 23, formed on the elongated body 20 communicates with the longitudinal bore 22 and extends longitudinally upward from the distal end of the elongated body 20 approximately 1¼ inches. A side slot 23′ may also be formed on the lower end of the elongated body 20′ which is used lock the elongated body 20 on the rack's lower framework.

As shown in FIG. 5, the clamping member 40 is a curved, wing-shaped structure approximately 4 inches in length. The clamping member 40 includes main and secondary jaw members 45, 50, respectfully, pivotally connected together at a center joint 42. Formed on the main jaw member 45 is the center bore 46 that slides onto the narrow neck section 24 on the elongated body 20. The main jaw member 45 and secondary jaw member 50 are aligned in the same horizontal plane. The secondary jaw member 50 is shorter than the main jaw member 45 and includes a finger gripping surface 51 that rotates toward the main jaw member 45 when the distal ends of the main and secondary jaw members 45, 50 are forced opened, (see direction of arrows in FIG. 3). Formed on the distal ends of the main and secondary jaw members 45, 50 are two complimentary shaped, one half openings 47, 52, respectively, that surround and encapsulate the center stem 92 on a piece of stemware 90 to securely hold the stemware 90 on the rack 95.

In the preferred embodiment, the biasing means is a transversely aligned split ring 62 that extends between the main and secondary jaw members 45, 50. The split ring 62 extends through small openings 49, 54 formed on the two jaw members 45, 50. The two unattached ends 63, 64 of the split ring 62 press against the outer surfaces of the two jaw members 45, 50 to forcibly push them together.

As shown in FIG. 5, the accessory 10 is designed so that one to four clamping members (two shown) may be used with one elongated body 20. Because the neck section 24 is octagonal in cross section and is engaged by the center bore 46, each clamping member 40, is locked in position on the elongated body 20 to prevent the pieces of stemware 90, 90′ from moving on the rack 95 when the dishwasher is operated. Because the center bore 46 is slightly larger in diameter then the neck 24, each clamping member 40 slides vertically and freely over the neck section 24, thereby enabling the apparatus 10 to be used with different sizes of stemware 90. In the preferred embodiment, the apparatus 10 is made of heat tolerant plastic or similar material. While the clamping member 40 is described in the preferred embodiment to be a wing-shaped structure. It should be understood that it is not limited to this particular shape.

In compliance with the statute, the invention described herein has been described in language more or less specific as to structural features. It should be understood, however, that the invention is not limited to the specific features shown, since the means and construction shown is comprised only of the preferred embodiments for putting the invention into effect.
